Case Study Discussing the differences between FRCC values for maritime Douglas-fir - western hemlock systems in the Oregon Coast Range and western Cascades than for ponderosa pine – Douglas-fir systems in the Northern Rockies.

Discussion on possibilities as to why LANDFIRE FRCC appears to underestimate the effect of widespread invasion of annual grasses into sage shrublands in southeastern Oregon and to overestimate departure in central Montana grasslands.

LANDFIRE FRCC in Wyoming Big Sagebrush in southwest Wyoming shows moderate to high departure and sharp boundaries between adjacent subsections. while FRCC in desert shrub systems in southwestern Arizona is ubiquitously low, even though significant impact from invasive plants is expected.

The Landscape Fire and Resource Management Planning Tools (LANDFIRE) Program, with the assistance of numerous regional specialists, has assigned fuel attributes to all lands across the United States for the purpose of predicting wildland fire behavior. Various methodologies have been employed and several data versions have been created over the past 10+ years. The basis for the entire suite of fuel attributes, both surface and canopy fuel depictions, began with the allocation of the surface fuel model.

This table lists the minimum information LANDFIRE needs to continue to improve our products. Additionally, more specific details are requested from stakeholders when possible to further assist with data improvements. Not all attributes are needed for each observation or event. Any information you can provide is useful as long as the minimum requirements are met.

Attribute tables for LANDFIRE grid data are available on the Data Distribution Site. Generally, these attribute tables provide information pertaining to the grid class value along with class descriptions or labels for these values. Attribute tables, such as the Existing Vegetation Type, provide additional attribute fields that can provide crosswalk links to other classification themes. Color mapping fields are also provided within the attribute tables, providing a standardized, consistent LANDFIRE color mapping schema for these data layers. The attribute files are in comma separated value (csv) format that can be easily converted to other formats to meet user needs.

Table in PDF format, Environmental Site Potntial represents the vegetation that could be supported at agiven site based on the biophysical environment. As used in LANDFIRE, map unit names represent the natural plantcommunities that would become established at late or climax stages of successional development in the absence of disturbance."

Table in XLSX format, Existing Vegetation Type represents the current distribution of the terrestrial ecological systems classification developed by NatureServe for the western Hemisphere. A terrestrial ecological system is defined as a group of plant community types (associations) that tend to co-occur within landscapes with similar ecological processes, substrates, and/or environmental gradients.
